Multi-factor Authentication FAQ - Saved credentials
Multi-factor authentication is intended to stop people who have your password, not your laptop. If thieves have both your laptop and your StarID password, then they would be able to log in to your laptop and use it to access your Office 365 account if your authentication token was still valid. If it expired, then they would be confronted with mutli-factor authentication and would not be able to access your Office 365 account via your stolen laptop.
